Our Featured Procedures

State-of-the-Art Care Using Advanced Technology

We can design and create customized restorations on-site.

At Lashen Dental Group, we have incorporated some of the latest tools into our practice for more efficient, effective treatment, including digital x-rays, intraoral cameras, and a digital scanner. These devices can provide a comprehensive assessment of your oral health and assist our doctors in making early diagnoses, as well as allow us to personally tailor each treatment plan.

Our state-of-the-art laboratory allows us to provide crowns and veneers in a single visit. 

With our digital scanning system, impressions can be made more quickly and comfortably than traditional methods. We can then send this information to our fully equipped dental lab. This allows us to create a range of restorations, including crowns and porcelain veneers, in a single visit. We also administer anesthesia using The Wand, a computer-controlled anesthesia delivery system. With this device, injections are virtually painless and we are able to precisely control the levels of anesthetic throughout treatment.
